Abstract (en)
A device, a method of using such a device and a method for making such a device for threading floss between dental structures. The threading device is formed of a tube including a handle portion (22) and a blade-like portion (24). A charge of dental floss (34) is retained in the tube of which a lead portion (36) extends through a tip aperture (28) formed at a terminal tip (30) or end of the blade-like portion (24). The lead portion (36) is coated with a material to stiffen the same to further facilitate insertion of the device between dental structures. The device is formed by providing a tube and inserting a charge of floss (34) therein. The tube and floss materials have different melting points such that the melting point for the floss material is greater than the melting point for the tube material. The tube is heated to its respective melting point whereupon a portion of the tube is formed into the blade-like portion (24). During the forming process, the lead portion (36) of the floss (34) is retained in place such that upon completion, it extends through the tip aperture (28). <IMAGE>
